Pump efficiency monitoring

Robertson Technology

Energy efficiency & monitoring

Pump and blower efficiency and flow-rate monitoring using the thermodynamic method.

Based in Western Australia

Serving the world

Robertson Technology markets its products and services internationally, with a focus on energy efficiency and associated environmental benefits. To date, products and services have been provided to 15 countries.

There is a worldwide requirement for accurate monitoring of pump and blower efficiency and flow rate to keep them in optimum condition, thereby reducing energy and maintenance costs, improving plant reliability, and alleviating greenhouse gas emissions.

Efficiency

Reduce energy and maintenance costs through precise monitoring.

Reliability

Improve plant reliability and reduce the risk of catastrophic failure.

How it works

The thermodynamic method

Energy lost in a pump ends up as heat. Measuring it gives efficiency and flow rate without a conventional flow meter.

Differential temperature

Measurement of differential temperature (often to an accuracy of 0.001 °C) across the pump or blower.

Pressure & enthalpy

Combining temperature with pressure data provides efficiency via the thermodynamic method (change in enthalpy).

Flow rate

Measurement of electrical power then provides the flow rate with high precision.

Configurations

System configurations

Portable units are used for investigative work and regular monitoring. Fixed installations provide on-line predictive monitoring for critical pumps and interface with station optimization software to achieve the lowest electricity costs.

  • Portable units — investigative work and regular monitoring for water utilities, mines and power stations
  • Fixed installations — on-line predictive monitoring for critical and high-power pumps, interfacing with station optimization software
